How do you write each number as a power of the given base: -64; base -4?

Answer 1

Julia Adams

#-4^3 = -64#

It is a real advantage to know all the powers up to 1,000.

64 is one of the powers of 4. #" "rarr4^3 = 64#

It is possible to have negative powers as long as the index is an odd number.

#-4^3 = -64#

Even indices always give a positive power.

#(-4)^2 = +16 " and " (-4)^4 = +256#
